41. Its luminescence quantum yield is 0.90. 42. What, if any, benefit the fungus derives from the luminescence is uncertain. 43. The luminescence is photochemically stable and its quantum yield is ~ 0.65. 44. Melissa Buzzeo : Near : a luminescence 87. 45. Luminescence dating of the fossils was done by optically stimulated luminescence ( OSL ).46. Luminescence dating of the fossils was done by optically stimulated luminescence ( OSL ). 47. The introduction of the Transfiguration mandorla intended to convey the luminescence of divine glory. 48. The Spanish only succeeded in preserving and increasing the luminescence in the now isolated bay. 49. Optically stimulated luminescence ( OSL ) was developed in 1984 by David Huntley and colleagues. 50. He was the first to presume that metal impurities affect the colour of the luminescence .
